The country could be set for one last blast of summer heat this week with temperatures in some parts expected to reach 21°C.

However, this might be hard to believe for some people in Lancashire who have just put their summer clothes away and turned the heating on for the first time in months.

Here’s everything you need to know about when the warmer weather is expected to hit the UK – and if Lancashire will feel the benefits.

When will the warm weather hit the UK?

Speaking to National World, Jim Dale, meteorologist for British Weather Services, said: "The warmer weather will kick in from mid-week onwards, and we could see 21C in parts of the country by Thursday,”

“High pressure building from the continent will bring a change from the wetter, windier weather to drier, sunnier conditions,” he added.

Mr Dale notes Hurricane Sam has much to do with the warm conditions we will see this week.

"The remains of Hurricane Sam will veer towards Iceland as it moves across the Atlantic, this will mean it will miss the UK but pull warm air in from the south” and “as we are now in October, we can call this an Indian Summer,” he said.

"This could last through the week or possibly longer into the mid-month when we expect to see a return to something more usual for the time of year."

What is the weather forecast in Blackburn?

According to Met Office forecasts, the hottest day of the week will hit tomorrow (8 October) and temperatures across the North West will reach highs of 21°C.

In Blackburn with Darwen, the temperature is set to be slightly cooler than the national average – but it’s still warm enough to keep the heating off!

However, you might still need a raincoat at hand.
